Definitions

the invention relates to a cable lead for a pacemaker electrode, with a cladding tube made of electrically insulating, elastic material and at least one conductor arranged therein for electrical stimulation current pulses, the conductor comprising a core made of a metal of high electrical conductivity and a jacket made of a has corrosion-resistant, non-toxic metal.
a cable lead for a pacemaker electrode is known from US Pat. No. 3,749,101. Silicone rubber is used as the material for the cladding tube.
the wire-shaped conductor arranged in the elastic cladding tube consists of a corrosion-resistant alloy of 20 to 50% Co, 15 to 30% Cr, 5 to 10% Ni, up to 18% Fe, 1 to 10% Mo, up to 3% Mn, up to 0.3% C and 0.01 to 0.09% Be.
a cable feed line for a pacemaker electrode is also known from US Pat. No. 4,273,137.
an electrical conductor is arranged, which consists of a plurality of electrically conductive fibers, these fibers having a jacket made of a corrosion-resistant, non-toxic metal alloy, such as stainless steel or a cobalt-based alloy, which has a core made of a Encased metal with high electrical conductivity.
a corrosion-resistant, non-toxic metal alloy such as stainless steel or a cobalt-based alloy
Silver, copper, silver-based alloys or copper-based alloys are used as core materials.
the large number of electrically conductive fibers is arranged in a shell, which in turn consists of the same corrosion-resistant, non-toxic metal as the sheath material of the individual fibers.
the single fiber consists of a tube serving as a jacket, which is filled with the metal with high electrical conductivity.
the object of the invention is to provide a cable feed line in which electrical power losses are reduced to a minimum and which ensures good biocompatibility.
the conductor is a sheathed wire produced by pulling, the sheath of which is made of a metal from the group of tantalum, titanium, zirconium, niobium, titanium-based alloy, platinum, platinum Iridium alloy, platinum-palladium alloy and platinum-rhodium alloy, wherein the shell wall thickness is in the range of 0.0025 to 0.035 mm and the core diameter is 0.04 to 0.3 mm.
copper and copper alloys have proven to be suitable as materials for the core.
Zr, Ti, Be, Fe, P, Zn or 'Sn are particularly important alloying elements.
Examples of such alloys are CuZr0.15, CuTi4, CuBe2, CuBel, 7, CuBe0.7, CuZn28, CuZn37, CuSn6, CuSn8 or CuFe2.
a cable has proven itself as a cable feeder in which the core of the sheathed wire consists of CuZr0.15 or CuBe2 and the sheath made of tantalum, the outer surface of which is anodized.
Pt-Ir alloys with up to 40% Ir the rest of Pt, Pt-Pd alloys with up to 50% Pd, the rest of Pt and Pt-Rh alloys with up to 40% Rh, the rest of Pt have proven to be suitable as sheath materials, advantageously alloys made of PtIrlO, PtPdl0 and PtRh10.
a preferred example of sheath materials made of titanium-based alloys are the alloys TiA16V4 and TiA15Fe2.5.
the elastic cladding tube in which the sheathed wire is arranged, is made of plastic, such as, for example, silicone rubber or polyurethane. It is so elastic and flexible that it can only be introduced into the heart chamber by being carried along by the blood stream.
cable feed lines designed according to the invention are distinguished by long service lives.
the batteries required for the electrical stimulation current pulses have a very long service life.
the biocompatibility of the wire-shaped conductor is ensured by using the sheath materials mentioned in claim 1.
Fig. 1 an embodiment of a cable feed line according to the invention is shown.
Fig. 2 shows a cross section through the sheathed wire.
Fig. 1 is made of plastic, for. B. silicone rubber, existing cladding tube, in which the conductor 2 is arranged for electrical stimulation current pulses.
the conductor 2 is formed from four coiled sheathed wires, the thickness of the individual sheathed wires being 0.11 mm.
the core of a sheathed wire consists of CuZr0.15, the sheath made of Ta, the outer surface of which is anodized.
An electrical resistance of 1.75 ⁇ was measured for such a 60 cm long cable feed line - this length corresponds to the cable feed lines normally used. A value that is about an order of magnitude smaller than cable feeds on the market.
the pacemaker electrode is designated, with 6 the connector, which is connected to the pacemaker control unit.
the core is denoted by 3 and the sheath by 4.
the wall thickness of the jacket is 0.012 mm
the diameter of the core is 0.086 mm.
Usual wall thicknesses for the jacket are in the range of 0.0025 to 0.035 mm
core diameters are in the range of 0.04 to 0.3 mm.
